The Prime Day deals are still rolling in, and here’s some good ones for the audiophiles. Bose QuietComfort headphones are available for a record-low price of $199. That’s more than 40 percent off the usual list price for one of our favorite picks for a noise-canceling Bluetooth headset. 

Bose has a reputation for excellent audio tech and the QuietComfort line has adjustable EQ so you can tailor the sound balance to your tastes. The wireless headset promises “all day battery life,” but you can also opt to use them in a wired configuration. There are also multiple colors available at this reduced price, including the Blue Dusk hue that’s an Amazon exclusive.

The base headset isn’t the only one currently on sale. The Bose QuietComfort Ultra headphones are also discounted to $329 for Prime Day. This high-end model impressed us with its combination of top-notch noise canceling and spatial audio technology. It also has touch controls built into the earcups and the headset can be turned off with head motions. The Ultra model offers the same 24 hours of battery life as the main model.

If you’re already set with over-ear headphones, you might be more interested in the Bose QuietComfort Ultra Earbuds. Those are on sale for $229, almost a quarter off the usual retail price. This set has the same blend of spatial audio and noise canceling as the Ultra model, but in earbud form. We found the Immersive Audio mode was a big battery drain, but otherwise these Bose earbuds are a stellar choice for in-ear headphones.

Amazon just announced a coming expansion of its same-day prescription delivery service, with 20 more cities and affiliated metro areas entering the program next year. This expansion will open up the feature to nearly half of US residents.

The company said it’s currently embedding pharmacies in many of its same-day delivery facilities to allow for the advanced rollout. The service already exists in cities like Miami, Phoenix and Seattle, but next year it’ll be coming to Boston, Dallas, Minneapolis, Philadelphia and around a dozen more national hotspots.

Amazon says that in most cases “a customer can order medication by 4PM and receive it at home by 10PM.” This is achieved via traditional delivery methods, though the company has been testing prescription delivery drones in Texas.

The delivery service is available via Amazon Pharmacy, which offers free shipments of prescriptions to Prime members. The service first launched in 2020 and has allowed the company to enter the healthcare space in a major way. Amazon also operates a virtual healthcare service, which is available in all 50 states.

The company recently boasted that it has doubled the number of customers it delivers prescriptions to. This number will likely shoot up even higher once the service becomes available in more cities next year.

GM is charting a course away from its Ultium battery system. The company is dropping that standardized approach in favor of a wider range of battery cell chemistries and physical formats.

The automaker had hoped that, by adopting a unified system across all of its EVs as well as other products, it would be able to reduce costs and ship them faster. The plan was to pack the flat pouch-style Ultium cells into a variety of modules depending on what was needed for each EV.

Things haven’t gone smoothly, as Ars Technica notes. Among other things, COVID-19 slowed down the company’s EV roadmap and there were problems with the robots that assembled the modules.

“It now makes business sense to transition from one-size-fits-all to new program-specific batteries,” Kurt Kelty, GM’s vice president of batteries, said at an investor event. The automaker hopes that switching from Ultium’s nickel cobalt manganese chemistry to lithium iron phosphate (LFP) battery tech will lower the cost of its EVs by as much as $6,000. As The Verge notes, Tesla and Ford are among those that use LFP cells, which are said to be cheaper and less complicated to manufacture. The second-gen Chevy Bolt, which is slated to arrive in late 2025, will use such batteries.

GM plans to build a new battery research facility at the Warren Tech Center in Michigan. The team there will explore cylindrical and prismatic cells in addition to the pouch format. Researchers will also look into alternative battery chemistries.

The shift in battery strategy comes as GM chases profitability in its EV division. The company said it’s getting close to that point. It’s on track to build and sell around 200,000 EVs this year. GM now claims to be the number two EV seller in North America behind Tesla.

Green Day’s Dookie is an all-timer of an album and, if you were fortunate enough to catch the band on the road this summer, you’ll know the trio sounds as good as ever. Audio quality, however, was not at the forefront of the band’s latest release: demasters of every Dookie song on ridiculous and outdated formats to mark the record’s 30th anniversary.

While other classic albums often get remasters for big anniversaries, Green Day (with the help of of an art studio called Brain) went in a lo-fi direction by re-releasing the music on defunct and/or inconvenient formats in very limited editions. As a result, you can hear what “Basket Case” sounds like through a Big Mouth “Billie” Bass, listen to “Welcome to Paradise” via a Game Boy cartridge and enjoy (or not) “When I Come Around” emanating from a wax cylinder.

Other formats the demasters appear on include an answering machine, toothbrush, animatronic stuffed animal, floppy disc, doorbell, Fisher Price record, HitClip (remember those?) and, be still my beating heart, MiniDisc. Meanwhile, “All By Myself,” an ode to self-love sung by drummer Tré Cool, actually sounds kind of sweet through a music box.

You can hear what each of the demasters sounds like on the Dookie Demastered website. But if you want to own one of them, you’ll need to be lucky. Only between one and 50 of each demastered format is available and they’re priced between $19 and $99, but thankfully it’s not a first-come-first-served scenario. There’s a random drawing and you’ll get the chance to buy one of the items if your name’s pulled from the hat.

Demastering is becoming more of a trend, especially in video games, but this is simply a bizarre way to listen to an album as important for punk rock as Dookie was. It would be very cool to have an X-ray record of “Coming Clean” in my collection, though. (For the tape, Green Day did release a deluxe anniversary edition of the album.)
